Intrepyd

Intrepyd is a python module that provides a simulator and model checkers in form of a rich API, to allow the rapid prototyping of formal methods algorithms for the rigorous analysis of circuits, specifications and models.

  • Circuits of inputs, latches and combinational nets over booleans, bounded and unbounded integers, reals and floats.
  • A simulator, and four engines: bounded model checking, k-induction, backward reachability and IC3/PDR, whose proofs are checked; a portfolio runs them all in parallel, and answers with the first of them.
  • Front-ends for Lustre and IEC 61131-3 Structured Text (PLCopen XML).
  • Traces as pandas data frames.
pip install intrepyd

Wheels are available for Linux (x86-64, glibc 2.28 or newer) and Windows (x86-64), for python 3.11 or newer. Each one carries the intrepid model checking library for its platform, so there is nothing else to install.

import intrepyd as ip
from intrepyd.engine import EngineResult

ctx = ip.Context()
int8_t = ctx.mk_int8_type()
c = ctx.mk_latch('c', int8_t)
ctx.set_latch_init_next(c, ctx.mk_number('0', int8_t),
                        ctx.mk_add(c, ctx.mk_number('1', int8_t)))

bmc = ctx.mk_bmc()
bmc.add_target(ctx.mk_eq(c, ctx.mk_number('5', int8_t)))
bmc.set_current_depth(5)
assert bmc.reach_targets() == EngineResult.REACHABLE

The documentation, the source and the issue tracker are on GitHub; a collection of experiences using Intrepyd is in the Formal Methods Little Corner.

Intrepyd is released under the BSD 3-Clause license. The intrepid library bundled in the wheels is proprietary, and its license, installed as intrepyd/LICENSE.intrepid, allows it to be used and redistributed freely, unmodified, as part of intrepyd. It links the Z3 SMT solver, released under the MIT license.
